Victron Energy Galvanic Isolator VDI-32 32A – $89.91 (Save 64%)
The Victron Energy Galvanic Isolator VDI-32 prevents electrolytic corrosion by blocking low-voltage DC currents that enter your boat through the shore power earth wire, protecting the hull, propeller, and shaft. It's the best fit for boat owners comparing corrosion protection solutions. Current price: $89.91, down from $249.05 — buy online today and apply coupon OUTPOST12 for an extra 12% off.
ABYC Compliance
The VDI-32 is built to galvanic isolator standards used in ABYC-aligned installations; always confirm your boat's certification requirements and have it installed by a qualified marine electrician where required.
Where to Install
Install the isolator directly behind your boat's 230V/120V shore power inlet, in series with the green earth/ground conductor.
How to Test a VDI-32
With shore power disconnected, measure across the isolator — it should show the diode threshold (about 1.4V each direction, anti-parallel pair). Conductivity below threshold in either direction means the diodes are intact.
VDI-32 vs Isolation Transformer
A galvanic isolator blocks DC corrosion currents at a fraction of the cost and weight; an isolation transformer fully isolates the AC circuit and also handles other fault scenarios but costs far more. For most recreational boats, the VDI-32 is the affordable, effective choice.
